OWEN H. JONES, OF HARTFORD, CONNECTICUT, ASSIGNOR TO FLORENCE M.POMEROY, F HARTFORD, CONNECTICUT.

BALL-coax.

To all whom it may concern.' v y Be it known that I, OWEN H.Y JONES, acitizen of the United States, residing at Hartford, in the county ofHartford and Stato of Connecticut, have invented a new and ImprovedBall-Cock, of which the following is a specification.

My invention relates more especially to devices lfor supplying water totanks used for various purposes and especially those used in connectionwith water-closets and an object of my invention among others is toprovide a ball cock that shall be simple in construction, etlicient inoperation and especially one that shall be free from objectionableleaking.

One form of ball cock embodying my invention and in the construction anduse 0f which the objects herein set out, as well as others, may beattained, is illustrated in the accompanying drawings, in which vlfigurerl is a topplan view of a ball cock embodying .my invention. v

Fig. :2 is a view in side elevation of my improved ball cock with partsbroken away in central section-to illustrate construction.

In the accompanying drawings the numeral 5 indicates the inlet sectionof my iinproved ball cock', this being the section to which a source ofsupply as an inlet pipe is attached in any suitable manner, and thenumeral G indicates the outlet section of the ball cock, that is, thesection-containing the chamber and from which the outlet 7 extends. Avalve seat S of any suitable form and construction is ysecured to thesection 5 ot' the ball cock, this seat being located within the chamber9 within the outlet section ot said cock. A valve plunger 10 is mountedfor reciprocating movement ina neck 11 constituting a part of thesection 6, a valve 12 being secured to the lower end of the plunger inposition to engage the valve seat 8. lars 13 project from the end of theneck 1l and a swinging block 1l is pivotally mounted between said ears,a float rod 15 being secured to said block as by means of a thumb screw1G. This float rod preferably extends into a hole in the block` thishole being located between the pivot 26 support- Specification ofLetters Patent. Patented Jan. 8, 1918.

ing the block and the pivot 4 connecting the block and link.

v This block 14 has a groove 17 in its under side, the bottom of thisgroove comprising ashoulder against which a link 18 abuts to limit bothlthe opening and closing move.- ments of the valve. .Said link ispivotally attached to said block and to the plunger 10 and extendswithin a groove in the plunger (as shown in dotted lines in Fig. 2 ofthe drawings) and into the groove 17. This link has a beveled or curvedpart 19 to permit swinging movement of the link in the opening andclosing movements of the valve, the extremity 20 of the link at one endof the beveled part constituting a closing stop. The edge of the link ator near the termination of the curved partY at the other end thereofconstitutes with the edge 21 of the groove 17 an opening stop.

f The closing stop 20 is not effective when a new valve 1:2 is in place,but when said valve becomes worn to a certain extent then the closingstop 20 comes into play to determine the position of the block 1l in theclosing movement of the valve and thus prevents the pivot 4 from passingthe dead center and thus allowing the float rod 15 with its float torise, owing to its buoyancy, sufficiently to again open the valve afterit has been closed in therising movement of said float. The stop formedby the curved part of the link near its lower end striking the bottom ofthe slot 17 determines the position of. the valve when it is open.

' In order to prevent the passage of liquid along the plunger 10 and outat the end of the neck 11 I provide a relief groove 22 preferably ofannular form in the plunger 10. This groove intercepts any liquid thatwould have a tendency, from the pressure or other- Wise, to flow alongthe sides of the plunger out of the chamber 9, and I also provide meansfor retaining any liquid that may thus How along the sides of theplunger Within the body of the valve and for compelling such liquid toflow through the outlet 7. This I accomplish by providing a diaphragm 23extending partly across the chamber within the section 6 of the valve,

this diaphragm forming the upper part of the chamber 9 and also forminga relief chamber 24 located Within the val-ve body.V

This chamber 2A4 opens bya' 'mgutli '2 5-into the chamber 9 and fromthence any liquid in the. relief Chamber. .will How. threueh the loutlet 7. f In theA fo'rin'ofthedeyice as Shown herein the relief groove221s` "normali-y' closed by the Wall separating the reliei'and outletchambers.
